Real-life Dual-Task Training for Older Adults at Risk to Fall: A Pilot Clinical Trial (REAL-DTT)

2026年11月5日 更新者：Colorado State University

Older adults have difficulty optimizing two tasks at once and typically experience greater interference than younger adults when dual-tasking, meaning that there is greater decline in performance of at least one task when comparing single and dual-tasking. Difficulty dual-tasking may actually predict falls in community-dwelling older adults. Dual-task training has been shown to improve cognitive outcomes (attention, memory), motor outcomes (balance, gait), and dual-task performance in older adults; however, most dual-task training involves simulated tasks that do not reflect functional dual tasks in the real world. Greater dual-task improvements could be seen when training functionally specific tasks. One way to increase task specificity is to offer real-life, contextually-relevant, dual-task training embedded in instrumental activities of daily living (IADLs). Therefore, the purpose of this study is to assess feasibility, acceptability, and preliminary efficacy of a real-life dual-task training program for older adults at risk to fall compared to fall prevention education.

干预/治疗
实验性的：Real-life Dual-Task Training

Six real-life dual-task training sessions with explicit focus on motor and cognitive components of instrumental activities of daily living. Training occurs with a licensed occupational therapist, and activity selection and grading is guided by the therapist and participant.
行为的：Real-life Dual-Task Training

The intervention is Real-life Dual-Task Training (Real-DTT) which uses instrumental activities of daily living training with explicit focus on the cognitive and motor elements and progressive complexity. A structured debrief is used to determine when to focus attention on cognitive vs. motor tasks in order to reduce fall risk. The Real-DTT sessions will be delivered once a week for 6 weeks and delivered by a licensed occupational therapist. Real-DTT is a modified version of occupational therapy, with a protocol tailored to the participants.
有源比较器：Fall Prevention Education

Six guided fall prevention education sessions combining evidence-based fall prevention topics, CDC patient fall prevention handouts, NIH/NCOA fall prevention education resources, and tailored discussion utilizing behavior-change techniques.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Cognitive Dual-Task Effect
大体时间：Baseline, week 6-7, week 12-14

Cognitive Dual-task Effect is a percent change from single to dual-tasking: ([dual-task-singletask]/single-task) *100. The cognitive condition is verbal fluency. The dual-task condition combines verbal fluency (cognitive) through the Timed Up & Go dual task.
Baseline, week 6-7, week 12-14
Motor Dual-Task Effect
大体时间：Baseline, week 6-7, week 12-14

Motor Dual-task Effect is calculated as a motor percent changes from single to dual-tasking: ([dual-task-singletask]/single-task) *100. The percent change calculates the difference in time in seconds to complete the Timed Up & Go from single to dual-task.
Baseline, week 6-7, week 12-14

次要结果测量

结果测量
措施说明
大体时间
Performance-Based Assessment of Self-Care Skills
大体时间：Baseline, week 6-7, week 12-14

The Performance-Based Assessment of Self-Care Skills (PASS) is a performance-based measure of activity performance. The PASS is validated for individual instrumental activities of daily living (IADLs) and therefore we will use the 14 physical emphasis IADLs, and the 4 cognitive emphasis IADLs.
Baseline, week 6-7, week 12-14
Activities-Specific Balance Confidence Scale
大体时间：Baseline, week 6-7, week 12-14

A standardized 16-item self-report measure of balance confidence, scores range from 0-100% with higher scores indicating greater confidence in balance when performing various functional activities.
Baseline, week 6-7, week 12-14
Acceptability of Intervention Measure
大体时间：week 12-14

The Acceptability of Intervention Measure is a self-report measure used for intervention feedback. The assessment is 4 questions in total scored 4-20 with greater scores indicating greater acceptability.
week 12-14
Intervention Appropriateness Measure
大体时间：week 12-14

The Intervention Appropriateness Measure is a self-report measure used for intervention feedback. The assessment is 4 questions in total scored 4-20 with greater scores indicating greater appropriateness.
week 12-14
Feasibility of Intervention Measure
大体时间：week 12-14

The Feasibility of Intervention Measure is a self-report measure used for intervention feedback. The assessment is 4 questions in total scored 4-20 with greater scores indicating greater feasibility.
week 12-14
